I need help nowww!! 16 points

Answer:

A: x = 0

B: x = All real numbers

Step-by-step explanation:

A.

Any number to the power of (0) equals one. This applies true for the given situation; one is given an expression which is as follows;

(6^2)^x=1

Simplifying that will result in;

36^x=1

As stated above, any number to the power of (0) equals (1), thus (x) must equal (0) for this equation to hold true.

36^0=1\\x=0

B.

As stated in part (A), any number to the power (0) equals (1). Therefore, when given the following expression;

(6^0)^x=1

One can simplify that;

1^x=1

However, (1) to any degree still equals (1). Thus, (x) can be any value, and the equation will still hold true.

x=All\ real \ numbers
